Texas Instruments provides a recommended PCB layout in the ADS5413IPHP evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The ADS5413IPHP datasheet provides general guidelines for analog input filtering, but the optimal filter design depends on the specific application's frequency range, noise environment, and signal characteristics. Engineers can use tools like TI's FilterPro software or consult with TI's application engineers to design a custom filter that meets their specific requirements.
While the datasheet specifies a maximum clock frequency of 125 MSPS, the actual maximum clock frequency may be limited by the specific application's requirements, such as the analog input frequency, signal-to-noise ratio, and desired resolution. Engineers should consult with TI's application engineers to determine the optimal clock frequency for their specific application.
The ADS5413IPHP requires calibration to achieve optimal performance. Engineers can use the device's built-in calibration modes, such as the offset calibration and gain calibration modes, to calibrate the device. Additionally, TI provides calibration software and documentation to guide the calibration process.
The recommended power-up sequence for the ADS5413IPHP is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps to ensure that the device powers up correctly and minimizes the risk of latch-up or other power-up related issues.
